The equivalent conductance of solution i...

The equivalent conductance of solution is …… .
[If cell constant is `1.25 cm^(-1)` and resistance of `N//10` solution is `2.5xx10^(3) Omega`].

A

`2.5 Omega^(-1) cm^(2)" equiv"^(-1)`

B

`2.5 Omega^(-1) cm^(-2)" equiv"^(-1)`

C

`50 Omega^(-1) cm^(2)" equiv"^(-1)`

D

`5.0 Omega^(-1) cm^(2)" equiv"^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
D
`k=("Cell constant")/("Resistance")=1.25/(2.5xx10^(3))=5xx10^(-4) Omega^(-1) cm^(-1)`
Equivalent conductance `=(kxx1000)/(M)`
`=(5xx10^(-4) xx1000)/(1//10)`
`=5Omega^(-1) cm^(2)" equiv"^(-1)`
